Influence of corrosion on the seismic vulnerability of a low-rise, poorly constructed RCC building

Abstract

Seismic vulnerability assessment methods have been used by engineers and policy-makers as a tool for various engineering and economic applications during the last several decades. These methods were developed for building typologies representing a building stock. Member deficiencies due to poor quality of design, construction or maintenance are not explicitly taken into account in most of these methods. This paper quantifies the influence of member-level deficiencies due to corrosion on the seismic vulnerability of a low-rise, poorly constructed RCC building. Typical design and construction practice prevalent in Andaman and Nicobar Islands have been considered, which is both a highly seismic zone and has highly corrosive environment due to the saline and humid environment.
